摘要 光纤频率传递系统可以实现高精度的频率信号传输,但在长距离频率传递中,信号光功率不断损耗,需要使用光放大器进行补偿。基于双级放大器的良好性能,设计了一种可用于光纤频率传递的双级双向掺铒光纤放大器(Dual-stage Bi-EDFA),并对该方案进行了实验和分析。结果表明,该方案实测增益最高可达27.5dB,噪声指数为3.56dB,增益平坦度低于0.3dB。将该方案应用到160km频率传递系统中,可以实现1.09×10^(-14)@1s和2.36×10^(-17)@10000s的频率传输稳定度。 Fiber-optic frequency transfer systems enable high-precision transmission of frequency signals.However,in long-distance frequency transmission,the signal optical power is constantly lost,which needs to be compensated by using an optical amplifier.Based on the good performance of two-stage amplifier,a two-stage bidirectional erbium-doped fiber amplifier(Dual-stage Bi-EDFA)that can be used for fiber-optic frequency transfer is designed,and the scheme is experimented and analysed.The results show that the measured gain of the scheme is up to 27.5dB,the noise figure is 3.56dB,and the gain flatness is less than 0.3dB.The scheme is applied to a 160km frequency transfer system with 1.09×10^(-14)@1s and 2.36×10^(-17)@10000s frequency transmission stability.
